What is your IQ?

[perpetuus]

I guess my IQ is not high enough for this joke. So the other guys are also INTP but with higher IQ?. But they are all 3 INTP? Or is the skinny guy INTP and the other 2 some sensors. Ok, I get it, they are all 3 INTP and the thing about muscle is a metaphor for intelligence. Or something..?

Yes, I think the meme was supposed to be playing on the idea or the stereotype of those types having high IQs and it might act as a metaphor or analogy for how one with an average IQ might feel in the presence of those with higher IQs. Muscles being analogous to intelligence, in the case of this meme.

Don't sell yourself short. IQ is an overrated metric.
